Abstract

Вимірювальний пристрій з гальванічною розв'язкою для вимірювання змінної напруги (U1) у лінії електропередачі мережі електроживлення, що включає вимірювальну схему (35), яка має мікроконтролер, схему живлення (33), що може здійснювати живлення вимірювальної схеми (35), а також трансформатор (Т), який має первинну обмотку, що живиться за допомогою мережної синусоїдальної напруги (U1) і з'єднану із зазначеною лінією електропередачі, а також вторинну обмотку з напругою (U2), причому обидві обмотки з'єднані із зазначеною вимірювальною схемою (35) і також зазначеною вимірювальною схемою (33). Схема живлення (33) і вимірювальна схема (35) включають відповідно перший і другий двопівперіодні випрямні елементи (BRG, BRG'), які відрізняються один від одного, при цьому другий випрямний елемент (BRG') сконфігурований так, щоб не створювати впливів навантаження на вторинну обмотку трансформатора (Т), а випрямний елемент (BRG') навантажений на повний опір (R') з високим значенням.Measuring device with galvanic isolation for measuring AC voltage (U1) in the power line of the power supply network, including a measuring circuit (35) having a microcontroller, a power supply circuit (33) that can supply the measuring circuit (35), and a transformer (T) having a primary winding powered by a sine wave (U1) and connected to the specified transmission line, and a secondary winding to the voltage (U2), both windings connected to the specified measuring circuit ( 35) and also aznachenoyu measuring circuit (33). The power circuit (33) and the measuring circuit (35) include respectively the first and second two-period rectifying elements (BRG, BRG ') that differ from each other, with the second rectifying element (BRG') configured so as not to create load effects on the the secondary winding of the transformer (T) and the rectifier element (BRG ') is loaded to full resistance (R') with a high value.
